Abstract：A copper oxide ore from Turkey with copper grade 2.09% was treated by flotation and leaching. The ore contained useful minerals of malachite, azurite and chrysocolla, as well as a small amount of copper sulphide, and had high oxidation rate and fine dissemination of useful minerals, which was easily muddy. The copper sulphide and part of malachite and azurite were enriched by flotation. The concentrate grade of copper from flotation was 25.04% with the recovery rate of 57.25%. The azurite and chrysocolla that remained in the tailings were leached by sulfuric acid, and the grade of copper decreased from 0.94% to 0.05%, the leaching rate of copper was 94.68%, leading to the high recovery rate of useful minerals.
